Chapter 398 Liu Qi's Star Destroyer Cannon Design

However, everything else about the star-destroying laser weapon is easy to deal with, the only difficulty is the superconducting energy storage.

If one wants to build a super-large superconducting energy storage station that can supply star-destroying laser weapons, the amount of superconducting materials consumed will certainly not be small. Therefore, how to obtain superconducting ore from Pandora has become another difficulty.

Fortunately, after the Na'vi people of Pandora fell in love with the super compound bow produced by Wandering Blue Star, they can now provide Wandering Blue Star with a considerable amount of superconducting ore every month.

After the emergence of the super-compound bow, the Na'vi naturally looked down on ordinary wooden bows and arrows. Therefore, more and more Na'vi people mined superconducting ore to replace their super-compound bows.

Therefore, in order to obtain more superconducting ores from the Na'vi, Wandering Blue Star has also set up a bow and arrow research and development department, whose purpose is to specialize in studying other functions of the super compound bow.

For example, the arrows that can be used for rapid climbing using bows and arrows, which were recently developed by the R&D department of the company.

The tail of this arrow is connected to a very tensile-resistant thin rope, and when the arrow hits the tree trunk, the rope is also shot out along with it.

Finally, by pressing the rope retractor tied to the wrist, the Na'vi can easily climb up a height or cliff hundreds of meters high.

In addition to this functional arrow, there are also some other gadgets to earn superconducting ore from the Na'vi.

Anyway, you can just cater to their interests and exchange some small commodities for the Na'vi's superconducting ore, so why not do it!

In the blink of an eye, more than three months had passed since Liu Xiu kicked out the construction of the star-destroying cannon. Three months later, the research institute finally gave Liu Xiu a preliminary design plan.

The first and most important point is that the height of this star-destroying laser cannon is ten times that of a planetary engine, reaching a height of 110,000 meters.

Its height is directly ten times the height of the planetary engine on the Wandering Blue Star. Of course, compared with the 35-kilometer diameter of the planetary engine's chassis base, the star-destroying laser cannon with a base diameter of only 200 kilometers is naturally much smaller.

The main reason why the base chassis is so small is that the laser cannon has no recoil, so there is no need to worry about the recoil causing damage to the crust of the Wandering Blue Planet.

After all, the thrust generated by the planetary engine when it sprays can reach 150 billion tons!

Of course, what is more crucial is that the muzzle diameter of this star-destroying laser cannon has reached an exaggerated level of one hundred kilometers.

Another reason why it was built so high instead of digging a pit underground is that the air at an altitude of 110,000 kilometers is thinner, thus reducing the attenuation of the laser when it penetrates the atmosphere.

However, the design drawing of the star-destroying laser cannon provided by the research institute is somewhat similar to the ruby ​​laser, the earliest solid-state laser launcher in human history.

Of course, the structure of this earliest ruby ​​laser is also very simple. It is generally composed of three parts: excitation energy, flash lamp, reflective cover, a reflector at each end of the resonant cavity, and the generating material, which is the ruby ​​rod.

When working, first the excitation energy is energized, and the xenon flash lamp emits high-frequency and strong scattered light. Direct irradiation and the focusing of the surrounding reflective cover gather the strong light on the generating material - ruby.

The main component of ruby ​​is aluminum oxide crystal, which is infiltrated with 5 parts per thousand of chromium oxide. The doping increases the speed of some valence electrons in the crystal, and also increases the tendency of valence electrons to absorb radiation and increase their own speed. Ruby absorbs the radiation of radial concentrated strong light, increases the speed of its own extranuclear electrons, and emits radiation in the low-energy direction. Because the ruby ​​is irradiated by strong light in the radial direction, only the axial direction is a low-energy area, so the ruby ​​irradiated by light emits radiation in the axial direction. Since the speed of the extranuclear electrons of the crystal is equal, the frequency of the radiation emitted in the axial direction is basically the same. The resonant cavity is composed of two reflectors installed at both ends of the ruby ​​crystal axis and separated by a certain distance. The rear piece is a total reflector and the front piece is a 95% reflector. The radiation emitted by the ruby ​​along the axial direction under strong light hits the reflector, passes through the ruby ​​crystal between the two reflectors, reflects back and forth, and travels repeatedly. The regular crystal of ruby ​​and the equal speed of valence electrons make the frequency and phase of the traveling light wave more consistent, the light intensity is rapidly enhanced and amplified, and the output is emitted from the front small hole with low reflectivity to form a laser.

It is precisely because the matter in the laser - the regular and constant speed movement of the electrons outside the nuclei of ruby ​​atoms - can radiate lasers with stable frequency and good coherence.

The fact of laser formation: the electromagnetic waves emitted by ruby ​​along the axis repeatedly travel between the regular crystals of ruby ​​and the valence and electrons at equal speeds, making the light waves regular and the frequency and phase more consistent. This provides us with an important concept - the frequency and phase of the electromagnetic waves in motion can be changed under the regularization and combing of external conditions.

Of course, to be more precise, the electromagnetic waves, that is, the light, are not changed, but the electromagnetic waves with regular frequency and phase, that is, the laser, are selected from a bunch of electromagnetic waves with chaotic frequencies.

Therefore, its photoelectric conversion efficiency is only a pitiful 0.1 to 1 percent, which is incomparable to the fiber laser with an efficiency of up to 30 percent.

Therefore, it is naturally impossible for the people from the Wandering Blue Star Research Institute to choose the ruby ​​laser as the design structure of the star destroyer laser cannon.

However, fiber lasers have power limitations, and it is difficult for them to reach the powerful power required by star-destroying laser cannons.

This is why fiber lasers cannot be used as super-large lasers.

In fact, it would take Liu Xiu at least several years to complete the research and design of the star-destroying laser cannon.

However, what Liu Xiu did not expect was that Liu Qi gave Liu Xiu another surprise. That's right, the reason why it only took three months to come up with the design of the star-destroying laser cannon was mainly due to Liu Qi's creative thinking.

It was precisely because of Liu Qi's inspiration that the design of the star-destroying laser cannon was realized so quickly.

Of course, the reason why Liu Xiu was able to obtain the design drawings of Liu Qi's star-destroying laser cannon was mainly due to Liu Xiu's answer that day.

That's right, after Liu Qi successfully designed the blueprints for the star-destroying laser cannon, he did not submit them for demonstration immediately, because Liu Qi was confident that his blueprints would be successful without demonstration.

But what Liu Qi was more afraid of was Liu Xiu's attitude, because Liu Qi was also afraid that Liu Xiu would use the star-destroying laser cannon he designed to really destroy a planet with life.

After all, according to what Liu Qi knew, the number of human lives living on that alien planet exceeded 10 billion.

So that day Liu Qi came to find Liu Xiu and asked Liu Xiu what he should do if the alien humans really fought to the death.

However, Liu Xiu shook his head and indicated that they were not going to conquer the alien humans, but to help the opposite sex. Then Liu Xiu told Liu Qi the story of Jack.

Especially when Liu Qi heard that Jack, as a soldier, lost both legs and the aliens had the ability to treat him but refused to do so, Liu Qi nodded in sympathy for Jack's situation and gave Liu Xiu the design drawings of the star destroyer cannon.
